Popis: We have previously shown that the inducible isoform of the cyclooxygenases, COX-2, is strongly expressed in pleural exudate leukocytes early (between 3 and 7 hr after irritation) during rat carrageenin-induced pleurisy. The present study further examined COX-2 expression and disclosed that mesothelial cells expressed COX-2 later (12 to 24 hr after irritation) in this model. A COX-2 inhibitor, nimesulide, lowered the intrapleural level of 6-keto-PGF1alpha and inhibited hyperplasia of the pleural matrix, suggesting that COX-2 expressed in mesothelial cells may play a role in the synthesis of extracellular matrix through formation of PGI2.
